  • Patent number: 10450703
    Abstract: The present application provides a tissue product comprising at least about 10 weight percent high coarseness fibers, from about 1.0 to about 10 weight percent synthetic fibers and less than about 10 weight percent long, low-coarseness cellulosic fibers. The high coarseness fibers may be cellulosic fibers having an average fiber length greater than about 2.0 mm and a coarseness greater than 17 mg/100 m, such as Southern softwood kraft pulp fibers (SSWK) derived from a pine in the Pinus subgenus, and the synthetic fiber is a non-cellulosic, thermoplastic fiber such as non-fibrillated polyethylene terephthalate (PET) fibers. In certain embodiments the tissue products may be substantially free from long, low coarseness cellulosic fibers, yet provide satisfactory strength, such as a geometric mean tensile from about 500 to about 1,200 g/3?, and softness, such as a TS7 less than about 11.0.
